Deferral of transmissions in wireless local area network

a wireless local area network and transmission technology, applied in the field of transmission deferral of wireless local area network, can solve the problems of inability to determine the level of signal detected by the first network from transmissions made within the second network, too attenuated or noisy to be decoded by the computing entities comprising the wireless network, and the limited use of physical hard wired infrastructure of commercial local area networks (lans) in widespread applications

Abstract

A wireless local area network comprising a plurality of computing entities communicating over a common communications frequency within a local area network operates a transmission deferral method whereby each computing entity defers its own transmissions if it receives a signal at said communications frequency which is above a threshold value set within said computing entity, and which is decodable. Each computing entity is capable of varying dynamically the value of its threshold level above which receipt of signals results in the computing entity deferring its own transmission. Received signals on the communications frequency which are less than the threshold value do not result in the computing entity deferring its transmissions, but are ignored by the computing entity. The threshold value is varied according to whether traffic from more remote signal sources are sufficiently intense that the local traffic cannot be decoded.

Description

[0001] The present invention relates to a method for maximizing channel use in a wireless network comprising a plurality of nodes. The invention is of particular significance where the nodes are computing entities, particularly but not exclusively a plurality of networked computers in an indoor environment.BACKGROUND TO THE INVENTION

[0002] Since the early 1970's, the success of the Ethernet project and other similar digital protocols has demonstrated the power and flexibility resulting from a plurality of computers sharing information across a digital network. However, until relatively recently, such commercial local area networks (LAN) were limited to a physical hard wired infrastructure in widespread applications.

[0003] In order to address a requirement for increased flexibility in computer networks there has been a drive to develop wireless local area networks whereby a plurality of computing entities such as personal computers, laptop computers, printers and the like exchange da...
